Forced lockdown of a city. Militarized police riding tanks in the streets. Door-to-door armed searches without warrant. Families thrown out of their homes at gunpoint to be searched without probable cause. Businesses forced to close. Transport shut down.

These were not the scenes from a military coup in a far off banana republic, but rather the scenes just over a week ago in Boston as the United States got a taste of martial law. The ostensible reason for the military-style takeover of parts of Boston was that the accused perpetrator of a horrific crime was on the loose. The Boston bombing provided the opportunity for the government to turn what should have been a police investigation into a military-style occupation of an American city. This unprecedented move should frighten us as much or more than the attack itself.

What has been sadly forgotten in all the celebration of the capture of one suspect and the killing of his older brother is that the police state tactics in Boston did absolutely nothing to catch them. While the media crowed that the apprehension of the suspects was a triumph of the new surveillance state – and, predictably, many talking heads and Members of Congress called for even more government cameras pointed at the rest of us – the fact is none of this caught the suspect. Actually, it very nearly gave the suspect a chance to make a getaway.

In the aftermath of the terrorist bombing—no lesser word will do—at the Boston Marathon, a major debate has broken out over the proper law enforcement procedures in two key areas: general surveillance and targeted searches. Many insist that a general right to privacy should limit the first, and that concern with racial and ethnic profiling should limit the second. Both of these overinflated concerns should be stoutly resisted.
